To all whom it may concern.

a i lie 11; known. that we, AnoLrii H. barren and (license W. NUBBE citizens of the United l 7 way track .i'aste inn; devices. and more par ticularly to rail anti-creepers.

it is well-known that the passage of trains over railway traelis tends to shift the traclcs longitudinally in the direction of the moveient of the trains. l l hen the trains run in. oppo. directions on the same tracks the tendon. of the .e-lis to creep in one dlreetio-n is eom'pensa ed by theirtendency to n, the opposite direetiom but when the i n only in one directiom as is the l. doi' b-le trael: reads, the creeping the rails is so considerable as 'z-ue unless prevented.

object of our invention is to l. anchor-inc deviees for raiL l i eel creeping h will securely reprovide impr road rails to u'erent l or shitting llllelj'tll'lll, wh

tain the rails against longitudihal movement relatively to the t me, and willbe automa. i1 cally actuated by any tendency oi the rails to creep to the rails ll'll 'e seeurely and eilect a more rigid resistance tothe ereeping ten dencv.

it still further oltijeet of our invention is to pro 'ide an improved. anti-creeper for ailroad rails which will be simple in construe; tion, convenient in, anplieation ellicient in operation and durable in use.

. (lur invention will be more iliullydisclosed hereinafter with reference to the accompak living drawings, in which the san'ie illustrated in. several. convenient and practical forms, and in whichl Figure 1 is a sectional view online 1., 1, ll ie'. l; his. 2 a perspective view of one of the clamping members; ljig". 3 a perspective view oi. the other clamping member.; Fig,

a """lBCtlVO view (it the other ol itlie said elm 11g members; and Fig. 13 a detail Referring more particularly to Figs. 1 to 5, inclusive,reference letter A indicates a railroad rail, the base a; of which is supported upon a tie I3. ()and Ddesignate interlocking clamping members which are adapted to be secured to the base oi. the rail adjacent the tie B and through the medium of the wedge G to prevent more inent of the rail towardthe tie. The elampinp; members Cl and D are provided with upwardly and inwardly extending flanges e and (Z, respectively, which. are adapted to engage the opposite sides oil? the base (i oi the rail. members whieh extend beneath the base of the rail are oppositely cut away, as shown at e and f, respectively) so that the two clamps transversely "aline. lhe clamplng members are provided with dewnwardly and inwardly inclined flanges E and ill, respectively, coextensive in length with the width of the portions of the clamping members which underlie the rail base. "the flanges E and F, therefore, nrojeei: acrossthe out away portions 6 and j, respectively, of the G deeigi'iates a wedge.

clamping members. having a. head (7 adapted to bear against the vertical surface of the tie B beneath. the rail base. The flanges E and li are tamered to correspond with the taper of the wedge G so that the wednelwill imifformly engage the said flanges throughout their lengtl and thereby when movedv relatively to such flanges exert a iuii'lorm pull. upon the clamping; members toward the rail base.

Our improved anticreeper """iay be veniently applied by first clamping memhers U and l" eonth e tancc. farther arm from the tie ll length ol. the wedge G. The WLll then inserted betiveen the oi 'erlarmed langi es T9 and F, and the clamping members, to-

efether with the wedge, morer'l toward the tie until the head 5/ of the wedge rests against the tie. The elampi L the tie, and eonsequently then "forced toward moved relatively to the wedge, as far as possible, so as to besecurely clamped to the rail base. Any tendency of the engaged por tion of the rail to creep toward the tie will cause the wedge G to more forcibly engage the flanges E and I and-thereby effect a tighter biting oi the flanges 0 and d of the clamping members against the rail base.

In Figs. 6, 7 and 8 we have showna slightly modified form of our mvention 1n which the flanges a and cl of the clamping members C and D are not located in transverse alinement, but are staggered, as clearly shown in'Fig. 7. In this form of ourinventio-n the clamping members are provided with downwardly extending curved flanges E and F, which are tapered longitudinally toconform to the taper of the wedge'G. The flange E extends beyond the adjacent I portion of the member 0 so as to underlie the portion of the clamp D, which lies beneath the rail base' In a similar manner the flange F extends beyond the portion of the clamping member 0, which underlies the rail base so as to extend across the under surface of the portion of the clamping member D which underlies the rail base. The form of our invention shown in Figs. 6, 7 and 8 is applied to the rail in the manner above described in connection with Figs. 1 to 5, inclusive, and operates substantially the same, except that the movement of the wedge relatively with respect to the engaged tapered flanges E and F draws the flanges c and d of the clamping members into I gripping relation with portions of the rail base which do not transversely .aline. In this form of our invention, as in theforn illustrated in Figs. 1 to 5, inclusive, the two clamping members interlock beneath the rail base in that each is provided with a flange extending beneath the base portion of the other, thereby affording an extended engagement with the wedge.

In Figs. 9 to 13, 1nclus1ve,'we have illustrated another specific embodiment of our inventionin which the wedge is formed integrally with one of the clamping members.

In said figures, reference character G designates one of the clamping members which is provided with an upwardly and inwardly projecting flange 0 to engage the rail base, and is also provided with the downwardly extending curved and tapered flange E pro,- jecting across the cut away portion-6 The cooperating clamping member I) is also. providedwithan upwardly and inwardly enftending flange c 2 to engage the opposite edge of the rail base. Formed integrally with the portion of the clamping member D which is adapted to underlie the rail base, is a wedge G provided witha head 9 This clamping member is cut away, as shown t F to. receive the'portion of the cooperating clamping member to which the flange E base.

thereof is connected. In this form of our invention the clampingmember D is engaged with the rail base adjacent the tie B and with the head of the wedge abutting against the adjacent vertical surface of the tie. The cooperating clamping member C isthen engaged with the opposite side of the rail base at a distance sufliciently far from the tie for the flange E to engage with the wedge G "The member C is then moved toward the tie so as to interlock with the cooperating clamping member D The v0 clamping members are forced toward the tie as tightly as possible so as to produce a tight gripping action between the clamp- 'ing' members and the railbase, owing to the relative movement of the wedge and the flange E Any tendency of the portion of the rail base which is engaged by the clamping members'to move'toward the tie tends to move the'member D relatively to the member C owing to the bearing of the'head g of the wedge against the tie.

From the foregoing description it will be observed that we have invented an improved anchoring device for preventing the creeping or shifting of rails relatively to the adjacent ties, which comprises transversely overlapping and V longitudinally interlocked clamping members having extended longitudinal engagement with an interposed wedge so that the two members will be uniformly and tightly drawn into gripping relation with the rail base through the medium of the wedge interposed between the clamping members and the-adjacent tie.

2. The combination with a railroad rail and supporting tie therefor, of a pair of clamping members engaging the opposite sides of the rail base and having long1-" tudinally and transversely overlapping portions below the rail base, and means bearing against the tie and extending between said overlapped portions to draw said mem; f

bers into tightly gripping contact with the rail base.

3. The combmation with a rallroad rail and supporting tie therefor, of a pair of clamping members engaging the opposite sides of the rail base comprising transversely overlapping portions beneath the railbase,

and also comprising depending longitudinally overlapping projections on the ends of said transversely overlapped portions, and means bearing against the tie and extending between said depending projections for drawing said members into tightly gripping contact with the rail.

4-. The combination with a railroad rail and supporting tie therefor, of a pair of clamping members engaging the opposite sides of the rail comprising transversely overlapping portions extending beneath the rail base, each of said transversely overlapping portions being cut away to receive the other portion, the ends of said overlapping portions having depending flanges thereon, and means bearing against the tie and interposed between said flanges to draw said members into tightly gripping contact with the rail.

5. The combination with a railroad rail and supporting tie therefor, of a pair of clamping members engaging the opposite sides of the rail comprising transversely overlapping portions extending beneath the rail base, each of said transversely overlapping portions being cutaway to receive the other portion, the ends of said overlapping portions having depending flanges diverging toward the tie and a wedge bearing against the tie and extending between said flanges to draw said members into tightly gripping contact with the rail.
